AUTOMATIC VALVE MEANS.

Application filed July 5, 1921. SerialNo; 182,478.

To all whom it may concern:

Be it known that I, Gnonen H. A.ND'ER-- son, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Automatic Valve Means, of which the following is a specification.

This inventionrelates to improved automatic valve means for regulating the water supply and maintaining the water level in v a boiler and controlling an auxiliary supply forthat purpose.

.The objects of this invention are to provide an improved float valve means for the purpose of controlling the water supply and auxiliary water supply in a boiler. Objects relating to details and economies of construction and operation will definitely appear from the detailed description tofollow. The objects are accomplished by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims. f

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawings forminga part of this specification in which: I

Fig. I "s a detail diagrammatic view of the structure in its relations to a steam boiler, a fragment only of whichis shown.

Fig. II is an enlarged longitudinal sectional view through the valve structure including part of the steam chamber taken on a line corresponding to line 2-2 of Figs.

III and IV.

Fig. III is a'diagrammatic sectional view on a line corresponding to line 33 in Figs.v

I and II the valve being in full lines.

Fig. IV is" an enlarged detail sectional view through the valve proper taken onthe line 33 of Figsl and II.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of reference refer to similar parts throughout the several views.

Considering the-numbered parts of the. drawingsby their numerals, l is a steam boiler, a fragment onlyof which is show-'11.

is the outer casing of the steam chamber for my improved valve structure the same being provided with asteam tight flanged. cover 3. 4t is the pipe connection from the upper part of the steam chamber to the steam space of the boiler.

is the flanged pipe connection from thecasingQ to the boiler below the water line. By this arrangement the water level within the casing 2 ismaintained at the water level of the boiler. I i

6 is the water supply pipe extending through the stuffing box 7 in the end of casing 2 and connecting atits inner end to the valve casing 8 which is disposed and arranged within the said chamber 2. The same is provided with a detachable cover 8. 9 is the outer chamber of the valve and 10 is the inner chamber formed by casing 10. An auxiliary central chamber .11 formed by casing 11' is also provided, the

chamber 10 being connected to the boiler j through the pipe 12 which isv arrangedto v the central casing l-1- of auxiliary chamber 11 is the balanced piston valve 13. This is providedwithlateral port openings 1l-14c towards its upper and 'lowerends adapted to open and connectthe outer valve chamber 9 to the inner valve'chamber 10. I

I A'reduced portionl5 forms a port through thebores 17 to connect the auxiliary chamber 11 to the inner chamber 10. (See Figs. II and IV.) l

In the up position the valve is completely closed. WVhen it is lowered slightly through the bores 16'tlieouter valve chamber 9 connects with the inner valve chamber l0 and delivers water from the pipe 6 through. the

valve, through the pipe 12 intothe boiler. When it is lowered a little farther the auxiliary chamber 11 is also connectedto deliver water from the auxiliary source through the pipe 12 into the boiler. v The chamber ll is connected by pipe 11'- to a city water main or other-auxiliary source of supply. (See Figs. I and III). The

valve 13 is provided with an upwardly ex tending stem 18 and the float lever 20 is connected thereto by a pivot 19, the end oi said lever 20 being tulcrun'ied at 21 at the upper end of the link 2 which is pivoted at 23 to the detachable top 8 of the valve chamber. The float lever 20 is provided with a float 24 for controlling the same.

From this arrangement it will be seen that the valve structure controls the supply 0'! Water delivered to the boiler. This is ordinarily supplied by a pump through pipe 6, the pipe having, of course, a suitable check valve.

\Vhen the Water level of the boiler d scends the float drops, opening the valve and permitting the supply from the pump to deliver through pipe (3 through. the valve from chamber 9 through chamber 10 through pipe 12 into the boiler. It the pump tails to act for any reason. or the supply from the main source tails, of course, the Water level will continue to lower. A farther drop of valve 13 permits the Water from the auxiliary source to enter through pipe 11 to chamber 11 through jortl'? to the central chamber, thus supplying and protecting the boiler.

Having thus described my invention What I claim as new and desire to secure by IJQli ters Patent is:

1. In a control valve structure,'tlie coinbination of the casing connected by suitable pipes at the upper portion to the steam space and at the lower portion to the Water space of a boiler, a supply pipe leading into the said casing and a delivery pipe leading therefrom Within the connecting pipe to the Water space of the boiler, a valve the casing of Which comprises an outer chamber connected to said supply pipe and an inner chamber connected to said delivery pipe, a central auxiliary chamber, an auxiliary supply connected to said central auxiliary chamber, a vertically disposed piston valve through bores on the opposite sides otthe said inner chamber and alined bores in the Walls of said central auxiliary chamber, the said valve being provided with ports timed to open successively to the inner chamber and to the central auxiliary chamber, a piston rod extending upwardly therefrom, a lever fulcruined on a suitable link to the upper portion of said valve casing pivotally connected to said stem, a float carried by said lever coacting for the purpose specified.

2. In a control valve structure, the combination of the casing connected by suitable pipes at the upper portion to the steam space and at the loiver portion to the Water space of a boiler, a supply pipeleading into the said casing and a delivery pipe leading therefrom Within the connecting pipe to the Water space of the boiler, a valve the casing of which comprises an outer chamber and an inner chamber, a central auxiliary chamher, an auxiliary supply connected to said central auxiliary chamber, a vertically disposed piston valve through bores onthe opposite sides oi the said inner chamber and alined bores in the Walls of said central auxiliary chamber, the said valve being provided With ports timed to open successively to the inner chamber and the central auxiliary chamber, a float and connection Within the said casing to control the said valve.
